Abstract
As the need for data secrets develops, so are systems that should make this secrecy possible. Today, most commonly used are classic cryptographic systems and cryptographic public key systems. Thanks totheintensedevelopmentofquantummechanics,inthelast30yearsawholenewkindofcryptography has emerged: quantum cryptography. Her biggest contribution is the ability to detect the interception of a communication channel by a third person. Is this really like that? The question is, if quantum cryptography is that good, why is it not widespread? The meaning of this paper is, on the one hand, define the basic mechanisms of quantum cryptography and protocols, and, on the other hand, point to the disadvantages of those relating to the possibilities of today’s circuitry and the security shortcomings in the protocols.
